Sinonasal adenocarcinoma is a tumor typically associated with exposure to occupational carcinogens. The International Agency for Research on Cancer (IARC) published several data in order to classify carcinogenic power of physical-chemical agents as far as sinonasal cancer is concerned.We report a clinical case of sinonasal adenocarcinoma observed in an 84 years old patient, without clinical history of past exposure to carcinogens, smoke and alcohol.A sinonasal adenocarcinoma in a patient without risk factors is extremely rare. It is very important to recognize this cancer at an early stage in order to give better survival rates to the patients.Carcinogens, Intestinal-type adenocarcinoma, Sinonasal cancer.L’adenocarcinoma naso sinusale è una neoplasia tipicamente associata all’esposizione di sostanze cancerogene occupazionali. Lo IARC (International Agency for Research on Cancer) ha pubblicato differenti tabelle che classificano, in base a studi e ricerche effettuate, le sostanze fisico-chimiche il base alla loro capacità di sviluppare il cancro nasosinusale. Numerosi ed approfonditi studi attribuiscono a questo tipo di neoplasia, un carattere prevalentemente occupazionale.
